Production Description

Alloy Steel A182 F5 Thread Coupling Dimensions means the coupling has threads at one or both ends. It is a commonly used accessory for industrial pipe connections. They are widely used in various industries, including chemical processing, petroleum, refining, marine waste treatment, utilities / power generation, industrial equipment, natural gas compression and distribution industries. Made of carbon steel, stainless steel, brass or aluminium. Working pressure 25 bar (16 bar for aluminium). They are available separately or as a set with an aluminium safety clamp to suit the inner diameter of a hose and its wall thickness. They can be also crimped with the appropriate ferrules for industrial hoses. They have female or male threads of different kinds: BSP, BSPT, NPT, NPS, metric, ACME, DIN11. Depending on the type of the thread, the connection comes with a flat seal, it is sealed on the cone (metal-metal) or on the thread (with PTFE thread seal tape, liquid or paste sealant).

Full Coupling: Both ends of the full thread coupling are threaded.

Half Coupling: One end of a half thread coupling is threaded and the other end is welded.

Shapes:

Straight: It is a kind of pipe coupling with the same diameter at both ends.

Reducing: The two ends of the coupling have different sizes

Product features

  • Use with air , water, oil, natural gas, steama.
  • NPT and FNPT threasa conform to ASME B1.20.1
  • Reducing coupling is used to connect two diffrent sizes of pipe. It is like concentric reducer that maintains a center line of the pipe but small in size.
  • Half coupling ids used for small bore branching from a vessel or large pipe. It can be threaded or socket type. It has a socket or thread end only one side.
  • Full threaded Coupling is used for connecting small bore pipes.  It used to connect pipe to swage or nipple. It can be threaded socket ends types.

Production Material

ASTM A182 F5 is a forging material specification for F5 grade alloy steel and is used for manufacturing bare forgings or forged and machined products for applications involving high temperature service.

It has a fairly high electrical conductivity among wrought alloy steels in the same category. In addition, it has a moderately high base cost and a moderately high embodied energy.
